Odd Bump on penis

Hi, I noticed a little bump type thing on my dick the other day on the skin of the underside of my penis. It almost feels like a pebble and feels like its almost coming out of the skin. I attached a couple pics below of it. I'm a little worried, but not too bad. I've never even had sex so I know it most likely can't be an STD, which is why I'm a bit worried as to what it could be. I took a pic of the whole area (theres a couple smaller things like it), and an up close pic of the bigger one itself.

I developed a similar nodule on my toe next to the left big toe. Thought I could have it sorted out by a chiropodist, but the doctor sent me to the hospital. After some serious anesthetic injections (and in full view of a operating team of ten) the specialist removed the bump, no bigger than your's but it was on the joint.
He declared if it came back - he'd have to dig deeper to the bone!
Now I don't think yours is so bad, I'd be inclined to monitor it and if it gets bigger, the nodule, not the penis.
See a doctor. Cysts down there are obviously a worry, though should never
be treated to a 'It will go away policy.'
Incidentally my foot was strapped up to a rigid sandal & hurt like hell for days.

Once when I was younger, early 20s, I could feel a tiny, hard lump when I was hard. I freaked out about it, thinking it was cancer or something and went to see a Urologist. He examined me and said it was..." most likely a damaged blood vessel, probably caused by too much pressure or...ahem...friction". Boy did I feel like stupid. It's still there.. Get it checked though, you'll feel better.
